FIRST EDITION of this fine drawing manual. The first plate in each series of pairs shows details, uncolored, and the second shows the same figure colored. The engraved frontispiece states that G. Testolini is an engraver, printseller & frame maker and follows with a list of his 'superfine' material offered for sale. VERY RARE: this is the only copy sold at auction in at least 35 years, according to American Book Prices Current, when it was last sold in the Plesch sale in 1976. Dunthorne 300 ("perhaps the finest of all drawing books of the period"); Nissen 1946; Prideax, Aquatint Engraving, 213.
